Thoresby Hall is a grade I listed 19th-century country house. It is one of four neighbouring country houses and estates in the Dukeries in north Nottinghamshire all occupied by dukes at one time during their history. The hall is constructed of rock-faced ashlar with ashlar dressings. It is built in four storeys with a square floor plan surrounding a central courtyard, nine window bays wide and eight bays deep.
Robert Pierrepont, 1st Earl of Kingston-upon-Hull acquired the Thoresby lands in 1633, but was killed in the Civil War in 1643. His son Henry Pierrepont, the 2nd Earl, built the first grand house, circa 1670. The house was remodelled for William Pierrepont, the 4th Earl, during 1685–87, after the earl had been granted the right to create the park by enclosure from Sherwood Forest.
The house was destroyed by fire in 1742, rebuilt...and then demolished again in 1868. The current building was completed in 1871.
